Answer:
Step-by-step explanation:
y = 2x - 2 (Linear)
Here, x = number of days
y = Total payment
Ashley paid $2 each day and gives $2 to her brother.
y = 2x²
This quadratic relation represents the total payment 'y' is twice as much as the number of days times itself.
y = 2ˣ
Exponential function represents that the total payment is twice as much as the number of days times itself.
A function is a mathematical rule which can be assigned a value.

Suppose a charity received a donation of 15.2 million. If this represents 34% of the charity's donated funds, what is the total amount of its donated funds?
Round your answer to the nearest million dollars.
Answer:
45 million
Step-by-step explanation:
Let [tex]x[/tex] be the total amount of its donated funds. We can set up the following equation:
[tex]0.34x=15.2\:[\text{million}][/tex]
Solving for [tex]x[/tex], we get:
[tex]x=\frac{15.2\:[\text{million}]}{0.34},\\x=44.7\:\text{million}\approx \boxed{45\:\text{million}}[/tex]
Answer:
45 million dollars (44.706...)
Step-by-step explanation:
15.2 ÷ 0.34 = 44.706
To check our answer:
44.706 × 0.34 = 15.2
Write the equation of the line that is parallel to the line y= -2x+3 and goes through the point (3, -6).
Answer:
y=-2
Step-by-step explanation:
because it's parallel --> a=-2
therefore we have y=-2x+b
the line goes through the point (3,-6) --> (-2).3+b=-6 --> b=0
Which of the following are solutions to the equation below?
Check all that apply
4x²+ 12x+ 9 =25
Answer:
B and C
Step-by-step explanation:
First, we need to get the left side equal to zero. Take away 25 from each side to get [tex]4x^2+12x-16 = 0[/tex].
We can use the quadratic equation of [tex]\frac{-b+ -\sqrt{b^2-4ac} }{2a}[/tex] to find the solutions.
Plug them in to get [tex]\frac{-12+-\sqrt{144 -(-256)} }{8}[/tex].
Simplify.
[tex]\frac{-12+-\sqrt{400} }{8}[/tex]
[tex]\frac{-12+-20}{8}[/tex]

Jason is training to run a marathon. His goal for this week is to run a minimum of 42 miles. So far this week, he has already run 18 miles. Which inequality could be used to determine the mean number of miles, m, he would need to run each day for 6 more days to achieve his goal?
Answer:
6m + 18 ≥ 42
Step-by-step explanation:
6m + 18 ≥ 42
------
No of miles per day=m
Total days=6
Target=42
Finished=18

In right triangles only:
The sine of an angle is equal to its opposite side divided by the hypotenuse. (o/h)
The cosine of an angle is equal to its adjacent side divided by the hypotenuse. (a/h)
The tangent of an angle is equal to its opposite side divided by its adjacent side. (o/a)
Since we're given an angle, its opposite side, and its adjacent side, we'll use tangent to solve for [tex]x[/tex]:
[tex]\tan 14^{\circ}=\frac{45}{x},\\x=\frac{45}{\tan 14^{\circ}},\\x\approx \boxed{180.49}[/tex].

2. What is the solution to the equation..
5m − (m + 4) = 2?
f. -1/2
g. 1/2
h. 1
j. 3/2
k. 3
Answer:
J. 3/2
Step-by-step explanation:
Let's solve your equation step-by-step.
5m−(m+4)=2
Step 1: Simplify both sides of the equation.
5m−(m+4)=2
5m+−1(m+4)=2(Distribute the Negative Sign)
5m+−1m+(−1)(4)=2
5m+−m+−4=2
(5m+−m)+(−4)=2(Combine Like Terms)
4m+−4=2
4m−4=2

know how long it will take an investment of $1,000
to earn $500 in interest if the yearly interest rate is 4.75%. Please answer fast and show work I will mark you as brain
Answer:
It will take 8.73 years.
Step-by-step explanation:
Giving the following information:
Initial investment (PV)= $1,000
Future value (FV)= $1,500
Interest rate (i)= 4.75% compounded annually
To calculate the time required for the initial investment to reach the objective, we need to use the following formula:
n= ln(FV/PV) / ln(1+i)
n= ln(1,500/1,000) / (1.0475)
n= 8.73
It will take 8.73 years.
